The tonsil is the largest lymphoid tissue in the pharynx. In childhood, it is an active immune organ, containing lymphocytes at various stages of development, such as T cells, B cells, phagocytes and so on. Therefore, it not only has humoral immunity and produces various immunoglobulins, but also has certain cellular immunity. Immunoglobulin IgA produced by tonsils has strong immunity, which can inhibit the adhesion of bacteria to respiratory mucosa, inhibit the growth and spread of bacteria, and neutralize and inhibit viruses. IgA can also enhance the function of phagocytes by activating complement. These are the most active between the ages of two and five.
From the point of view of immunity, tonsils should not be removed casually because of their immune function to the body. Tonsil hypertrophy in children is a normal physiological phenomenon. If hypertrophy does not affect breathing and swallowing and does not produce serious clinical manifestations, it should not be removed. Because excision may affect the local immune response and reduce the body's ability to resist infection. If tonsillitis recurs, which hinders breathing and swallowing and causes diseases such as rheumatism and nephritis, it should be removed in time. Generally, tonsillectomy in children should be performed after the age of four, and it is more appropriate to wait for two to three weeks after the inflammation subsides. However, if the attack is too frequent and can't wait, you can consider performing surgery after the attack subsides for a few days.
